Geometry (Congruence) Volume 1
This GeoGebra Book contains lots of discovery-based learning activities, investigations, and meaningful remediation worksheets that were designed to help enhance students' learning of geometry concepts both inside and outside of the mathematics classroom.
This GeoGebra Book also contains contributions from the following individuals:
Jennifer Silverman (https://www.geogebra.org/jennifer+silverman)
Steve Phelps (https://www.geogebra.org/stevephelps)
Dr. Ted Coe (https://www.geogebra.org/tedcoe)
Without their amazing talent and creativity, this resource would not have been possible.
